Curated OER
Does the increased use of fertilizers effect biodiversity?
Students conduct a hands-on lab activity in which they analyze a sample of water from a local stream or pond. They introduce a fertilizer solution into the sample and analyze and describe their findings.

Fertilizers & Grass Growth
Learners design an experiment to test the effects of common fertilizers on grass growth. They write or present a laboratory report responding to their observations and consider how fertilizers may affect the soil environment.

Week 3: Pollution Source and Effects
Lab groups set up an experiment to observe what happens over time in collected pond water when fertilizer, representing pollution, is added. This website does not include student lab sheets, but background information, materials, and...
Curated OER
Wetland/Estuary Structure and Functions
Students plant wetland plants in aquatic soil and regular soil. They test the effect fertilizers have on each and record the chemicals found in run-off water collected from each soil sample.

Eutrophication Lab
Learners examine the effects of detergents and fertilizers on aquatic life and describe algae. Students define the term eutrophication as the process by which a body of water, such as a pond, lake, stream, or river, has a sudden increase...
Curated OER
Structure of Seeds and Effects of Fertilizer on Plant Growth
Investigate the structure of seeds and the effects of fertilizer on the growth of plants. Young scientists observe a peanut and determine if it is a monocot or dicot plant. They plant seeds and make varying solutions of fertilizer, then...
Curated OER
Fertilizers, Pesticides and Human Health
Young scholars define several vocabulary terms related to chemicals and toxicology. Students calculate chemical concentrations in water and explain the toxicological principles that govern safety of substances. Young scholars conduct an...

Auxin: Indole-3-Acetic Acid (AAA), A Hormone with Diverse Effects: Synthesis and Applications
Students synthesize Indole-3-Acetic acid from 3-indolylacetonitrile. For this biochemistry lesson, students determine the effect of different concentrations of IAA on lima beans. They explain how hormones help in plant development.
Curated OER
The Effects of Alcohol and other Teratogens: A model using Zebrafish
Young scholars investigate the interference of various drugs on an embryo through experimentation. This is an open-ended lab to allow students to see effects of various chemicals humans choose to put in their bodies and create...
Curated OER
Fertilizer Frenzy
Students design and conduct an experiment testing the effect of fertilizers/soaps on algal growth. They estimate and predict, identify the variables, formulate a hypothesis, and record and analyze the data, presenting their findings in a...
Curated OER
Playing in mud puddles
Students examine the effects of rainfall on different surfaces and discuss water pollution. They review the water cycle and the uses of water in daily lifestyles. Students discuss the effects of soil run off in streams and rivers.
Curated OER
Fertilized Death Water
Students investigate the effect of chemicals on Platyhelminthes and planaria development. They observe the growth and development of planaria and investigate what fertilizer can do to living organisms when it is introduced into their...
Curated OER
Fertilizer Frenzy
Ninth graders design and conduct an experiment. They evaluate other's experiments. Students describe relationships between biological systems and the environmental contaminants. They work as a team to solve a problem.
Curated OER
Plant Reproduction
Students plant seeds in order to investigate and explore the questions: "How do seed companies develop varieties of plants?" and "What is the ideal plant?" Students will study related vocabulary and sketch seeds as they emerge. Students...
Curated OER
Eutrophication
Young scholars observe the effects of eutrophication and determine why it is harmful to aquatic ecosystems. They create mason jar ecosystems to observe the growth of algae in pond water. In addition, they observe the effect of...

Peace Corps Challenge Game: Soil Runoff
Students examine the causes and effects of soil runoff. In this environment lesson, students look at ways in which soil runoff is controlled. Students then play a game and discuss how the Peace Corps deals with soil runoff in African...
Curated OER
Flatworm Experiment
Sixth graders participate in an experiment in which they view flatworms and hypothesize the effect fertilizer has on flatworms when it is added to their environment. Students work in groups of four or five and view a slide, under a...
